imagine... a whole class of girls crowded around a chicken being dissected by the teacher. a slice of the scalpel and the neck is open, the teacher reaches in, pulls a tendon and the beak and eyes of the chicken open in a very possessed chiken sort of way, people could here the screams for miles.
I have poured concentrated (2M) sulphuric acid, concentrated bleaching solution (containing hypochlorite ion) and potassium iodide solution together!! a think layer of bubbles formed on top of the solution inside a 100 cm^3 beaker!! Then the whole laboratory was filled with poisonous chlorine gas and iodine gas !! I inhaled quite a lot of the gases, was afraid that I would kill my classmates and myself in the lab.
